The Sun Hydraulics DAAPPCN (DAAPPCN) is a pilot-stage, directional, 2-position, 2-way valve designed for pneumatic operation with a spring-return mechanism. This versatile cartridge is engineered to be used in either normally open or normally closed configurations, making it adaptable for various control applications. It is specifically crafted to fit the Sun T8A cavity, which allows it to be seamlessly integrated with Sun\u2019s pilot-operated mainstage valves. This integration simplifies the hydraulic system by eliminating separate pilot lines and requiring only one cavity machining for both control and primary functionalities. The DAAPPCN features a hardened spool and sleeve that ensure consistent operation, low leakage rates, and superior wear characteristics over its lifespan. It supports a maximum operating pressure of 5000 psi (350 bar), although the pilot port can accept up to 500 psi (35 bar). The minimum pilot pressure needed for operation ranges from 20 to 70 psi, calculated based on the formula provided in its specifications. The preferred flow path through this valve is from port 2 to port 1. Installation of this valve requires careful attention to torque values; the main stage valve must be installed first to the correct torque followed by the T8A pilot control section into the main stage valve. The product also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This valve's compact design (.25 gpm/1 L/min capacity) and robust construction make it an excellent choice for systems requiring reliable directional control of pilot flows with minimal space and hardware requirements.

These pilot-stage, directional, 2-position, 2-way valves are pneumatically operated, spring-return cartridges and are available in either normally open or normally closed configurations. These cartridges are designed for pilot flow applications and utilize Sun's T-8A cavity so they can be used in conjunction with Sun's pilot-operated, main-stage valves.
- Utilizes the Sun T-8A 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage pilot or vent-to-operate cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-position, 2-way pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
- Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
- The preferred flow path through the valve is port 2 to port 1.
- Different pilot control port options are available. See Option Selection for details.
- Hardened spool and sleeve provide consistent operation, low spool leakage rates and superior wear characteristics.
- The minimum pilot pressure required to operate the valve is determined by the following formula: pilot pressure = 20 psi + pressure @ Port 1 divided by 100. This results in a pilot pressure range of 20 to 70 psi. In metric; pilot pressure = 1,4 bar + pressure @ Port 1 divided by 100. This results in a pilot pressure of 1,4 to 5 bar.
- All ports will accept 5000 psi (350 bar) with the exception of the pilot port which accepts 500 psi (35 bar) max.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
